Release time:
2024-10-11
Corundum castable is a high-performance building material, which is widely used in the construction of various industrial equipment, building structures and wear-resistant floors. The use of corundum castables can improve the wear resistance, impact resistance and durability of the project. The use of corundum castables will be described in detail below:
Preparation of 1. materials
1. Ensure that the quality of corundum castable meets the relevant standards.
2. Prepare an appropriate amount of water for adjusting the consistency of the castable.
2. construction steps
1. Clean the base: clean the oil, dust and debris on the construction surface to ensure that the base is flat, dry and free of cracks.
2. wet base: before construction, wet the base with water to improve the cohesiveness of corundum castable and base.
3. Mixing: mix corundum castable and water evenly according to a certain proportion to ensure no agglomeration and dry powder.
4. Laying: the mixed castable is evenly laid on the construction surface, and the vibration rod is used to eliminate bubbles and ensure compacity.
5. Leveling: Use scraping ruler and other tools to level the castable to ensure that the surface is smooth.
6. Joint treatment: if there is multi-layer construction, it is necessary to set expansion joints between each layer to avoid shrinkage and cracking.
7. Maintenance: After the construction of corundum castable is completed, it needs to be maintained to keep moist and avoid dry cracking.
3. considerations
1. Strictly control the water-cement ratio and make the ratio according to the requirements of the product manual.
2. During the construction process, avoid long-term exposure to the sun, so as not to affect the performance of the castable.
3. Corundum castable has certain requirements for the construction environment, and construction should be carried out at a temperature above 5 ℃ to avoid construction in rain and snow weather or low temperature environment.
4. Before construction, read the product manual carefully to understand the performance and usage of the product.
5. In case of any problems during use, contact the supplier in time for consultation.
4. acceptance criteria
1. After the completion of the construction of corundum castable, the surface should be smooth, no cracks, no holes.
2. After the expiration of the curing period, the wear resistance, impact resistance and other performance testing to ensure compliance with relevant standards.
In short, the correct use of corundum castable needs to follow certain construction methods, pay attention to construction details and maintenance work to ensure the durability and safety of the project. Hope the above content is helpful to you.
